 # repo-scan
 
 > Every ecosystem has its own dependency manager, but no tool looks across C++, Android, iOS, and Web to tell you: how much code is actually yours, what's third-party, and what's dead weight.
 
-## When to Activate
+## When to Use
 
 - Taking over a large legacy codebase and need a structural overview

-## Workflow
+## How It Works
 
 1. **Scan**: `/repo-scan` runs a pre-scan pass to classify files and detect dependencies
 2. **Analyze**: AI reviews the structured data and assigns verdicts per module
 3. **Report**: Interactive HTML report generated with verdict distribution and drill-down
